...ses for the synthesis of polyhydroxybutyrate (PHB) by Azotobacter vinelandii. The optimization of different carbon sources and various physical parameters was also performed. Highest yield of PHB was obtained by fermentation of 4% (w/v) wheat bran after 48 h of incubation with 4% (v/v) inoculum volume at pH 7.0 and 37oC. Among different nitrogen sources tested, 0.2% peptone gave the better yield (285 mg/100 mL), while yeast extract decreased ...
